Abstract
An infra-annular annuloplasty prosthesis is disclosed including a flexibly semi-rigid frame, a portion of which is shaped to conform to the scalloped configuration of the normal circumference of an arterial heart valve annulus. Axially projecting legs spaced circumferentially to correspond to the location of tissue adjacent to the valve commissures are provided for support and anchoring of the annulus-conforming portion to the dense fibrous tissues adjacent each commissure. The prosthesis includes a one-or two-part frame having scalloped upper and lower edges defining peaks and valleys. The upper edge is shaped to follow the contour of the tissue underneath the valve leaflets, and thus supports the leaflets and aortic wall from below. The lower edge is similarly scallop-shaped, but with less pronounced peaks and valleys than the upper edge, and is thus shaped to conform to the aortic annulus shape and provide support directly thereto.
